201259 - Miller 1/8" Contact Tip for FC-1150 Gun (25-Pack)

Precision and Performance with Miller 201259 Contact Tips

For professional welders utilizing the Miller FC-1150 MIG gun, the Miller 201259 Contact Tip is the standard for reliability and performance. Sized for 1/8-inch (approx. 3.2mm) welding wire, this contact tip is designed to handle the high current transfer required for heavy-duty welding procedures. Whether you are running flux-cored or solid wire of this significant diameter, the contact tip serves as the final point of electrical transfer to the electrode, playing a crucial role in arc stability and overall weld bead consistency.

The geometry of the 201259 tip is optimized for the FC-1150 gun, ensuring correct gas coverage and thermal management. A worn or inferior contact tip can cause micro-arcing inside the bore, leading to wire burn-back and frustration during critical passes. Miller's manufacturing process ensures that the bore is smooth and concentric, minimizing friction as the wire passes through. This is particularly important for 1/8-inch wire, which requires substantial feed force; any resistance at the tip can lead to bird-nesting at the feeder or irregular wire stick-out.

This package contains 25 contact tips, providing excellent value for high-volume welding stations. Regular replacement of contact tips is a best practice for maintaining optimal weld parameters. As the tip bore wears into an oval shape over time, electrical contact becomes intermittent, causing the arc to wander. By keeping a fresh Miller 201259 tip installed, you ensure that the current transfer remains efficient and focused. Upgrade your consumables inventory with these genuine Miller parts and experience the difference in arc control and wire feed smoothness that professional welders demand.
